Available for most of the more popular rifles and shotguns; the inexpensive, quality-made 5D sight. These sights are patterned after the Foolproof (FP). They have the same strength, lightweight, and neat appearance, but without the micrometer adjustments. Designed for rugged hunting use, the 5D sights are dependable and accurate. Positive locks. Clear unobstructed vision. No knobs or side plates to blot out shooter’s field of vision. Wherever possible, the manufacturers’ mounting screw holes in the receivers of the guns have been utilized for easy installation. The upper staff of the Williams 5D sight is readily detachable. It is only necessary to loosen one screw so that the upper staff slides easily in the close-fitting dovetail. The angular bushing locks this upper staff in a positive manner. A set screw is provided as a stop screw so that the sight will return to absolute zero upon detaching and reattaching. The material used in the manufacture of the Williams 5D sight is one of the highest grade alloys obtainable. There has been no sacrifice of quality as we are using one of the most expensive, highest tensile strength alloys that money can buy. Laboratory tests show that the material used has a tensile strength approximately 25 greater than mild steels. This high-grade alloy is finished with an anodize in a deep blue-black that adds even further to the strength of the sight by creating an extra hard surface. *Note: two positions for aperture holder to give double the amount of windage. Standard thread sizes, the same as used on the Foolproof (FP), permit the use of a wide range of apertures for all sighting conditions. Twilight apertures interchangeable.
